Sed festival

The sed festival (also known as Heb Sed or Feast of the Tail) was an ancient Egyptian ceremony which was held to celebrate the continued rule of a pharaoh. It is supposed that the name refers to an animal's tail that was normally attached to the back of the pharaoh's garment in the early periods of Egyptian history. Despite the antiquity of the Sed Festival and the hundreds of references to it throughout the history of Ancient Egypt, the most detailed records of the ceremonies - apart from the reign of Amenhotep III - come mostly from "relief cycles of the Fifth Dynasty king Neuserra... in his sun temple at Abu Ghurab, of Akhenaten at East Karnak, and of the Twenty-second Dynasty king Osorkon II... at Bubastis."
